Description

Technical Field

[0001] This invention relates to the field of hydraulic control technology, and in particular discloses a vehicle and hydraulic system with an erection function. Background Technology

[0002] In the field of machinery, special-purpose vehicles generally require self-supporting capabilities during operation, and some vehicles also need erecting functions. Currently, self-supporting and erecting mechanisms typically use hydraulic drives, with the mechanism's movement driven by manually adjusting the opening of a multi-way valve via a control handle. A traditional manually controlled hydraulic system, such as... Figure 1 As shown, it mainly consists of a left-starting vertical balance valve 101, a left-starting vertical cylinder 102, a right-starting vertical balance valve 103, a right-starting vertical cylinder 104, a vertical multi-way valve 105, a return oil check valve 106, a priority valve 107, a left front horizontal cylinder 108, a left front vertical cylinder 109, a right front horizontal cylinder 110, a right front vertical cylinder 111, a left rear horizontal cylinder 112, a left rear vertical cylinder 113, a right rear horizontal cylinder 114, a right rear vertical cylinder 115, a vertical hydraulic lock 116, a self-supporting multi-way valve 117, a return oil filter 118, a pump power assembly 119, and a hydraulic oil tank 120.

[0003] Its working principle is as follows: After being pressurized by the pump power assembly 119, the hydraulic oil enters the self-supporting multi-way valve 117. By manually controlling the operating levers S1 to S5 of the self-supporting multi-way valve 117, the left front horizontal cylinder 108, left front vertical cylinder 109, right front horizontal cylinder 110, right front vertical cylinder 111, left rear horizontal cylinder 112, left rear vertical cylinder 113, right rear horizontal cylinder 114, and right rear vertical cylinder 115 are driven and controlled respectively. The hydraulic oil reaches the erection multi-way valve 105 through the self-supporting multi-way valve 117 and the priority valve 107. By controlling the operating levers S6 and S7, the left erection cylinder 102 and the right erection cylinder 104 are driven and controlled. The return oil flows back to the oil tank through the return oil check valve 106 and the return oil filter 118. The left erection balance valve 101, the erection multi-way valve 105, and the vertical hydraulic lock 116 have the function of load holding.

[0004] Currently, the hydraulic control system of vehicles with erection function has the following technical disadvantages:

[0005] 1. Low precision in erection. The operating speed of a multi-way valve is typically adjusted manually using a lever. This method requires a high level of operator skill and results in low precision in repetitive movements.

[0006] 2. The self-supporting mechanism is cumbersome and has low operating efficiency. The self-supporting mechanism generally uses four sets of horizontal and vertical hydraulic cylinders as power drives. After the four sets of horizontal hydraulic cylinders extend into place, the vertical hydraulic cylinders begin to adjust the support. The process is relatively complicated and relies on manual adjustment, resulting in low operating efficiency.

[0007] Therefore, the low accuracy and efficiency of existing vehicles with erection functions are urgent technical problems that need to be addressed. Summary of the Invention

The sliding frame is connected to the swing frame, one end of the sliding cylinder is connected to the sliding frame, and the other end of the sliding cylinder is connected to the erection carrier. During operation, the swing cylinder swings backward, and then the vertical cylinder extends until the support contacts the ground, completing the self-supporting swing and vertical movement. When the sliding cylinder drives the sliding frame and the erection carrier to move backward to a set position, the erection cylinder extends to drive the erection frame, the sliding frame, and the erection carrier to be erected to the set position, completing the sliding and erection movements.
